l Specification of Letters Patent.

Appiicatioii filed January. 2e, 1920. serial No. 354,197.

To all whom t may concern.'

Be it known that I, Jol-TN O. TEnnELnxa citizen of the United States, residing at San Bernardino, in the county of San Bernardino and State `of California, have invented new and useful Improvements in Gas-Engine Stoves, of which the following is a specification.

This invention relates to cooking apparatus and has for its object to provide an improved gas engine stove, and a further object is to provide a stove of this kind that can be readily attached to the exhaust manifold or pipe or other convenient exhaust part of anvinternal combustion engine so that the heat thereof may be utilized for cooking purposes when desired. The invention consists of thel construction, the combination and in details and arrangements of the parts an embodiment of which invention is illustrated in the accompanying drawings and described and claimed herein.

Figure 1 is a side elevation of a portion of au internal combustion engine to which the invention is shown applied, a portion of the device being broken away.

Fig. 2 is a transverse sectional view on line 2-2 of Fig. 1.

Fig. 3 is a plan view of the device shown in Fig. 1 .f v

Fig. 4 iis a detail elevational and sectional view of a detached heating tube.

The invention is adapted to be used in connection with any given type of internal combustion engine a form of which is indicated at 2, the attaching means of the invention being readily changeable or constructed to adapt it to a given motor.

Ordinarily engines have an exhaust tube or flue on one side as indicated at 3 and this tube is tapped at desirable locations as at t to receive the threaded end 5 of a heating tube 6 preferably cylindrical in form and having its threaded end providedvwith an internal seat or shoulder 7 against which may abut a valve'head or piston 8. This valve or piston 8 has a push rod 9 shown as jointed at 10 to provide relatively movable sections so that when the outer'threaded end 11 of the rod is unthreaded from the head 12 at the outer end of the heating tube 6 the outer section of the rod 9 can be dropped down to a position shown in Fig. 2. The upper portion of each of the tubes 6 is longitudinally slotted at 13 so that as the valve 8 is drawn outwardly along the slot the heated gases may play directly upon a cooking utensil of suitable shape and construction indicated at 15 in Fig. 2. The chambers within the tubes 6 communicate directly with the chamber in the exhaust manifold 3, and when the valves 8 have been withdrawn a suflicient distance to expose portions of the slots 13, a' portion of the heated gases and products of combustion that are passed through the exhaust manifold while the engine is in operation, will enter the chambers within said heating tubes, and as such gases give off their heat to the utensil 15, they will continue `to absorb heat from the exhaust gases passing through the manifold 3. There is no pro nounced circulation of heated gases through .the tubes 6, so that the heat of the utensil positioned on said tubes is effected through radiation.

This utensil is shown as removably insertible into an open topped box 16 having in its rear wall apertures 17 through which the threaded end of the valve casing or tube 6 can be passed and the outer wall of said box 16 is provided with apertures 18 through which the push rod 9 of the valve may extend.

To facilitate holding the box 16 in position upon the assembled heating tubes 6, said box may be inclosed on its ends and across the back by an outer stove casing 20 open at the bottom and having at the lower portion of its rear wall a lip 21 designed to slip down in between the body of the engine and the curved upper surface of the eX- haust tube 3. The cooking utensil 15 is provided with a lid or cover 22 having a steam vent or outlet preferably in the form of Van upwardly extending helical tube From the'above it will be seen that I have provided a device that is simple, inexpensive, substantial and that may be readily applied to a given type of exhaust ue or tube structure of internal combustion engines so that at any desired time the heat of the en gine when running may be utilized.

Various changes may be made without departing from the spirit of my invention as claimed.

I claim:

1. The combination with a gas engine and its manifold, of a plurality of tubes having their inner ends seated in said manifold, the outer ends of said tubes being provided with threaded openings, there being longitudinally disposed slots formed in said tubes, a

piston arranged for movement Within eachtube, a piston rod connected to each piston, the outer portion of which piston rod is threaded for engagement With the threaded opening in the outer end of the tube, a box inelosing said tubes, and a cooking utensil adapted to be positioned Within said box above said tubes.

2. The Combination with a gas engine and its manifold, of a vplurality of tubes having their inner ends seated in said manifold, the outer ends of said tubes being provided With threaded openings, therel being longitudinally disposed slots formed in said tubes, a

piston arranged for movement Within each tube, a piston rod connected to eaeh piston, the outer portion of Which piston rod is threaded for engagement With the threaded opening in the outer end of the tube, a box inolosing said tubes, a cooking utensil adapted to Abe vpositioned Within said box above said tubes, and a housing partially inelosing said box and theieooking utensil positioned therein.

In testimony whereof I have signed my name to this specification. Y
